The Problem: When you have no health, no ammo, and are about to hit a nest of enemies, the game auto-saves
The Solution: Chansey/Blissey
Chansey and its evolution, Blissey, are practically synonymous with healing in the Pokemon universe. They can be found at virtually every Pokemon Center, and have their own nursing school. Some of their attacks are even healing based, like Aromatherapy, Heal Bell, and Soft-boiled. Plus, they enjoy helping others out--the Pokedex notes that both will heal any injured person or Pokemon they come across. So who better to have on call when an auto-saves kicks in at the worst possible moment and you're left inches from KO in the path of an advancing enemy hoard? In the face of cold and uncaring game mechanics, a giant, compassionate egg Pokemon is just what the doctor ordered.
